Homework Statement



A rhombus has sides of length 100 centimeters and the angle at one of the vertices is 70 degrees. Approximate the lengths of the diagonals.

Homework Equations


Law of cosines


The Attempt at a Solution



I just want to make sure I have correct assumptions about a rhombus. If one vertices angle is 70 degrees, that means the opposite is as well. Since all four angles should equal 360 degrees, this means that the other remaining angles at 110 degrees each.

This is basically solving for a side of two triangle, I have two side lengths and an angle. My answers came out to about 114.7 centimeters and 163.8 centimeters.

Thanks Again :)
